Slash-and-burn in rainforests

Video (01:41 minutes):
How does the large-scale slashing and burning of the rainforest affect the climate?


The video describes how the practice of slash and burn has drastically increased over the past few years to make room for cattle raising and the cultivation of feed and vegetation for biofuels. The consequences for the Earth?s climate are devastating.

This video is an excerpt from the teaching DVD, "Der gefährdete Regenwald - Klima- und Artenschutz".

Means of lighting in comparison

Graphic:
An incandescent lamp, an energy-saving light bulb, and an LED are compared in terms of costs and efficiency.

The comparison as a table shows that although energy-saving light bulbs and LEDs are more expensive to purchase, their total costs are significantly lower over a period of 10,000 hours. In addition, they are much more efficient than an incandescent lamp.

How long will our energy sources last?

Chart:
A bar chart shows an overview of the remaining years of use of primary energy sources.

Of the fossil energy sources, petroleum will be the first to run out. What is the situation for the other fossil energy sources? Can new technologies delay the point in time when they run out? And is it really true that renewable energy sources never run out?
The time axis has a logarithmic scale.

Information and ideas:
Students learn that the logarithmic scale represents numbers ranging over several powers. More in-depth information regarding how long energy sources will last is provided in the "An overview of energy sources? information sheet.

Greenhouse effect

Video (01:24 minutes):
Explains the principle of the greenhouse effect and its importance for the Earth?s ecosystem.


The video starts with a brief introduction to the greenhouse gas carbon dioxide. A graphic then illustrates the functional principle of the greenhouse effect. Two things become clear: firstly, that life on Earth would not be possible without the greenhouse effect; secondly, that the human-induced greenhouse effect is having a harmful effect on the Earth. Carbon dioxide produced by humans is named as the cause of this harmful effect. The video ends on the following question for further study, "... and where does this additional CO2 come from?"

Information and ideas:
This video sequence can be followed, for example, by a detailed discussion of harmful greenhouse gases.

This video is an excerpt from the teaching DVD, "Das grüne Paradoxon - Warum die Erde wärmer wird".
